According to the current mock:
Colours of pointers as provided by @Jan_Dittrich:
Blue: fill #45a6ff, border #065cad
Yellow: fill #fdc44b, border #dda000
Also note that "pointer number 2" (blue one) should be moved above the x axis.
Also add a "shadow" dropped by the pointers to make it more distinct the pointers are interactive elements.
